X10SBA-L Temperature sensor

[Roots0]

I have just setup a new X10SBA-L running x64 full install, everything seems to be working well, however the onboard temp sensors seems stuck at 26.8c, its been like this for the past 2 days! Rebooting does't seem to change it.

sysctl -a | grep "dev.cpu.*.temperature" returns nothing.

Is this a support issue with *BSD and this motherboard? Here's a link to the manufacture: http://www.supermicro.co.uk/products/motherboard/celeron/X10/X10SBA-L.cfm

What setting are you using for your temp sensors?  Check System > Advanced > Misc.  It should be the "Intel Core" option.

Thanks thats added the individual core temps from the J1900 but the sensor which I guess is on the motherboard remains at 26.8c:

Maybe that sensor actually is 26.8C.  Many motherboards have an ambient air ("case") sensor which is far away from the CPU and other heat-generating components.

I don't think that's the case as the room temperature is fluctuating a good 5c or more. And the case has a small 40mm fan to remove heat.

I know this is a couple months back, but just wanted to chime in:

I bought a Supermicro motherboard a while back for a FreeNAS build, and it ended up having a bad temp sensor on it (the CPU fan would be at max RPMs all the time).  You can check the temperatures in BIOS to better see if it is a problem with the sensor itself or with the mobo interfacing with pfSense.  Just a thought.

I ended up RMA-ing the mobo and getting a new one.  The temp sensor works fine on the second one :)

Hi
so temp problem could be because of a defective motherboard?
